Citibank site does not allow my accounts to be shown(uploaded with my access field of ID and Password.... and always impossible to log in because it does not recognize my correct information as correct and sees it as false information...therefore does not recognize my ID and password and I am blocked out..

Also old information may not be deleted properly and causes confusion so site needs to be cleared of old useless information.

My old iMac's Firefox browser was automatically changed to ESR (by Firefox) since the computer could no longer update the operating system through Apple (obsolete). When I purchased a new iMac and migrated my data to the new computer, Firefox ESR is still the browser, and says it is up to date. I am assuming I should get the most current regular Firefox version, but don't know if there is an easy way to change the version and preserve all my saved passwords, logins, bookmarks, etc. Looking for guidance. Thanks
